4. Walter White ("Breaking Bad"): Sure, the seminal TV show is over, but that doesn't mean people won't be dressing up as antihero Walter White.

3. Jamie Lannister ("Game of Thrones"): Sure, he's now missing a hand, but c'mon ladies, that doesn't make him any less attractive. Expect to see plenty of guys trying to capitalize on the Jamie Lannister effect (advice to couples (or siblings): no Cersei and Jamie costumes, please).

2. Robin Thicke: From his "Blurred Lines" music video to twerking with Miley Cyrus in what can only be called an outfit inspired by the Joker, Robin Thicke has been bringing his hyper-sexuality to the forefront of public consciousness - and will be inspiring more than a few people at your local Halloween party.
